I guess my only comment is that Nikon builds some great scopes for the money. And they are hard to beat regarding the glass and some of the new coatings they are using. I have many scopes but is seems that one of my Nikons exceed expectations when it comes to gathering light at dusk and dim light situations. May want to get another Nikon for your new AR. But you will need one of the forward base mounts to provide proper eye relief if you have never mounted a decent sized scope on an AR Rifle.
The Constitution is not an instrument for the Government to restrain the people. It is an instrument for the people to restrain the Government!
Today, we need a nation of Minutemen, citizens who are not only prepared to take arms, but citizens who regard the preservation of freedom as the basic purpose of their daily life and who are willing to consciously work and sacrifice for that freedom."
